DENTAL FLASK.

Application filed. July 2,

This invention relates to. dental flasks,

more particularly to a fastening means for the sections of the body portion thereof and cover for the latter, and has for its object to provide in a manner as hereinafter set forth, a new, novel, strong, durable and ellicientfastening means whereby the sections of the flask body and cover for the latter are expeditiously secured together and quickly released when occasion requires.

lVith the foregoing and'other objects in view, the invention consists of the novel construction, combination and arrangementof partsas hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the clainiis hereunto appended,

In'tho drawings wherein like reference characters denote corresponding parts throughout the several views: 7

Figure 1 is a side elevation of a dental flask showing the adaptation therewith of a securing means for the-sections of the flask body and the cover for the latter in accordance with this invention, a

Figure 3 is a top plan view-of the c v r- Figure 4 is a top plan view of the upper section or ring' of the body portion of the flask. 1

Figurefi is a top plan View of the lower section of the flask body.

Figure 6 is a vertical sectional view of the flask.

Figure 7 is a are 6- .1 i Referring to the drawings in detail l desection online 7-57, Eign otestlhe lower or bottonrsec-tion of a dental flask and 2 the upper section orring of the flask. The section 2 as arranged iii-superposed relation with respect to thesection 1;. The cover or lid for the sect-ionQ isreferred togenerally by the reference character 3.

The section leis formed with twospaced pair of lugs and the lugs of one pair are indicja-ted at 4c and the lugs of theother pair at 5. The lugs of each pair are spaced-from each other and one pair is arranged at one end of the section 1 and the other pair at the other end thereof. The lugs a and 5 are flush with the top edge of the sectionl, Formed integral with the section 2, at each end thereof is a-depending lug 6. One of 1926. Serial N0. 120,172.

the lugs 6 associates with the pair of lugs 4. and the other lug 6 associates with the pair of-lugs 5 for positioning the sectionsl and 2 relatively to each other and further for preventing the shifting of one section relative to the other when the said sections are mounted in superposed relation."

The top edge of the section 2 isformed with a plurality of spaced notches, three in number and which are indicated by the reference character 7. notches 7 are protuberances 8 integral with the cover 3 and which seat in the notches 7 to prevent the cover 3 shifting relativelyto the section 2 when the cover and section 3 Associated with the i are arranged in superposed relation. The

protuberances 8, in connection with the notches 7, further provide means for setting up the cover 3 in proper position with respect to the section 2. a The fastening means curing the sections of the flask body and the cover for the latter together, as well asf or quickly releasing the same, comprises sets .of' coupling lug-s, a clampingdevice common to each set of lugs, and a wedge associated with each clamping device. As shown the fastenin g means includes three sets of lugs, and which project laterally with respect to the sections of the flask body and the .cover for the latter. The lugs of each set are arranged in superposed relation and clamped in spacedrela-tion with respect toeachother} The numberof lugs of each set is three. .As the lugs of each set are of the same construetion, the lugs of one set will bedescribed, as the description thereof will apply'to the lugs of the other set. The lugs of eachset-are indicated at 9, l0 and 11. The lugs 9, 10

for expeditiously seto each other, The setsof lugs areal-ranged and 11 are formed integral respectively with section 1. The lug ll has its bottoinformed with a transversely disposed groove extending from one side face to the other side face thereof, see Figure 7. The top of the lug 9 is formed with a semi-circular groove 12.

The groove formed in the lug 11 is indicated at 13.

Each clamping device, which associates with a set of lugs, consists of a vertically disposed inverted yoke-shaped member 14, having each of its arms 15 formed near its top with an opening 16. The opening 16 formed in the arms 15 or" the yoke 14 aline with each other. The bottom of the yoke or member 14 is indicated at 16 and the arms 15 in proximity to the bottom 16 are formed with openings, and the openings in one arm 15 is indicated at 17 and the opening in the other arm 15 is indicated at 18. The opening 17 is of the same height as the opening 18. The opening 17 registers with one end of the groove 13 and the opening 18 reg-- isters with the other end thereof. The openings 17, 18 in connection with the groove. 13 are provided for the passage of a wedge 19 from-either side of the member 14 and which coacts with a pin 20 for the purpose of clamping the lugs 9, 10 and 11 together, see Figure 7 The pin 20 extends through the opening 16 and is seated in the groove 12 see Figures 6 and 7. I

The lug 1O coacts with the lugs 9 and 11 V to provide a support therefor and prevent the breaking off of the lugs when they are clampedtogether. By driving the wedge 19 from one end thereof, that is the larger end'the lugs 9, 10 and 11 are clamped together and the coverotightly held upon the section 2, and further said sections 1 and 2, as well as the cover 3 are clamped together. By driving against the smaller end of the wedge 19, the sections of the flask-body and the cover are quickly released.

It isthought that the many advantages ot a dental flask .in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the'scope of the invention as claimed. p

hat I claim is:

1. A dental. flask formed of a plurality of body sections and cover, said sections and cover formed with means to prov de sets of laterally disposed superposed lugs, a

clamping device surrounding each of said closing each set of lugs, and Wedges extending through the lower end of said clamping devices and through the lower lugs of said sets for clamping the body sections and cover together. 7

3. A dental flask formed of a series of body sections and a cover, each of said sections and said cover formed with means to provide sets of laterally disposed superposed lugs, the means carried by the cover depending therefrom and opposing the upper of said. sections, a clamping device enclosing each set of lugs, Wedges extending through the lower end of said clamping devices and through the lower lugs of said sets for clamping the body sections and cover to-' gether, said cover provided with protuberances extending in the top edge of the upper of said body sections to prevent the latter shifting relatively to the cover, and said body sections having peripherally arranged interengaging means toprevent one shifting relatively to the other, the said peripherally arranged interengaging means formed integral with the bottom of an upper section and depending therefrom and further formed integral with the top of the lower section. 1 f

4. A dental flask including a lower body section, an upper body section, a cover for said upper section, each of said sections and said cover having coacting means to provide a plurality of sets of laterally disposed superposed lugs, the lugs projecting from the cover formed at the top thereof with a groove, the lugs projecting from said lower section formed at the. bottom thereof with 'a groove, an inverted yoke shaped member associated with each set of lugs, pins carried by 'said members and seated in said top grooves, wedges removably mounted in said members and extending through said bottom grooves to provide for the clamping of said cover and sections together.

5. A dental flask formed of superposed body sections and a cover for the upper sec t-ion, said sections and cover provided with coacting means to provide a plurality of sets oi laterally disposed superposed lugs, a pin seating in the upper lug of each of sai'd'sets, an inverted yokeshaped member associated with each set of lugs and depending therefrom, each of saidmembers having one of said pins extend through the upper end thereof, andflwedges extending through the lower lugs of said sets and through said members abovethe bottoms of these latter and coacting with said pins for clamping the lugs of said sets in abutting engagement to provide for the clamping of said cover and sections together.
